1. Unveiling the Truth: Tiresias is a blind seer who possesses the gift of prophecy. Oedipus seeks him out to inquire about the cause of a plague ravaging Thebes. Despite initial reluctance, Tiresias eventually reveals that Oedipus himself is the cause of the plague as he unknowingly killed his father, Laius, and married his mother, Jocasta.
2. Conflict and Irony: Tiresias's words create a conflict between him and Oedipus. Oedipus accuses him of being complicit in the conspiracy against him, leading to a heated exchange between the two characters. The irony lies in the fact that Tiresias speaks the truth, but Oedipus's pride prevents him from accepting it.
3. Symbolism and Foreshadowing: Tiresias's blindness is symbolic of the lack of insight and self-awareness that plagues Oedipus. It foreshadows the tragic downfall of Oedipus, who has been blind to his true identity and the consequences of his actions.
4. Catalyst for Self-Discovery: Tiresias's prophecy sets in motion a chain of events leading to Oedipus's self-discovery. Oedipus's rejection of Tiresias's words initially hardens his resolve to uncover the truth, but it eventually leads to his realization of his tragic fate.
5. Theme of Fate: Tiresias emphasizes the role of fate and destiny in the play. He represents the forces beyond human control that shape the lives of the characters, including Oedipus. His presence highlights the interplay between human agency and the inevitable course of events.
6. Moral Significance: Tiresias serves as a moral guide, challenging Oedipus's hubris and self-righteousness. His warnings highlight the consequences of arrogance, pride, and the pursuit of knowledge without the wisdom to handle its implications.
Overall, Tiresias serves as a pivotal character in "Oedipus Rex" by revealing crucial information, creating conflicts and irony, and adding depth to the play's themes of truth, fate, and human fallibility. His presence elevates the play from a mere tale of tragedy to a profound exploration of human nature and the complexities of the human condition.
